Old Pension Scheme (OPS) gives 50% of last drawn salary as guaranteed pension — best security, zero employee contribution. NPS is market-linked with no pension guarantee — higher corpus potential but uncertain monthly income. UPS (Unified Pension Scheme), launched April 2025, guarantees 50% of average last 12 months salary after 25 years of service, with 18.5% government contribution. For central government employees joining after 2025, UPS is clearly better than NPS. OPS is no longer available for new joiners.
1. Old Pension Scheme (OPS) — What Was It?
The Old Pension Scheme (OPS), also called the Defined Benefit Pension, was the pension system for all central government employees who joined service before January 1, 2004. It was fully government-funded — employees contributed nothing from their salary.
Key Features of OPS
- Pension amount: 50% of last drawn Basic Pay + DA
- Employee contribution: Zero — fully funded by government
- Dearness Relief (DR): Revised every 6 months — pension increases with inflation
- Family pension: 30% of last salary to spouse after employee’s death
- Gratuity: Up to ₹20 lakh tax-free on retirement
- Commutation: Up to 40% of pension as lump sum
Is OPS still available?
OPS was discontinued for central government employees joining on or after January 1, 2004. States like Rajasthan, Himachal Pradesh, Punjab, Jharkhand, and Chhattisgarh have announced OPS restoration — but this remains politically contested. Central govt employees joining after 2004 are under NPS or UPS.
2. National Pension System (NPS) — How It Works
NPS is a Defined Contribution scheme introduced in 2004. Both employee and government contribute monthly. The final pension depends entirely on market performance — there is no guaranteed pension amount.
Key Features of NPS
- Employee contribution: 10% of Basic + DA every month
- Government contribution: 14% of Basic + DA
- Investment: Equity, corporate bonds, and government securities
- At retirement: Minimum 40% must buy annuity (monthly pension)
- Remaining 60%: Lump sum withdrawal — tax free
- Pension amount: Depends on annuity rate at retirement — not guaranteed
NPS Risk: Since pension depends on market returns and annuity rates at retirement, an employee retiring during a market downturn may receive significantly lower pension. This uncertainty is the biggest criticism of NPS by government employee unions.
3. Unified Pension Scheme (UPS) — The New 2025 Scheme
UPS was announced in August 2024 and launched from April 1, 2025. It combines the best of OPS (guaranteed pension) and NPS (contributory nature). Existing NPS employees can also opt for UPS with a one-time switch option.
Key Features of UPS
- Employee contribution: 10% of Basic + DA (same as NPS)
- Government contribution: 18.5% of Basic + DA (higher than NPS’s 14%)
- Assured pension: 50% of average basic pay of last 12 months before retirement
- Minimum service: 25 years for full pension; proportionate for 10–25 years
- Minimum pension: ₹10,000/month guaranteed
- Family pension: 60% of employee’s pension to family on death
- Inflation protection: DR applied — pension rises with inflation
- Lump sum: 1/10th of monthly pay for every 6 months of service
UPS Key Advantage over NPS
UPS gives a guaranteed pension floor — even if markets perform poorly, you get 50% of average last 12 months basic salary. The government contributes 18.5% (vs 14% in NPS), and DR indexation ensures pension keeps pace with inflation — just like OPS.

5. Real Example — ₹50,000 Basic Pay at Retirement
Let’s calculate for a central government employee with ₹50,000 basic pay at retirement after 30 years of service. DA assumed at 50% (so ₹75,000 effective pay).
📊 Monthly Pension Comparison — ₹50,000 Basic Pay, 30 Years Service
*NPS pension is estimated — depends on actual market returns and annuity rates at retirement time.
Key insight on long-term value: After 20 years of retirement, OPS and UPS pensioners receive much higher effective pension than NPS due to Dearness Relief. At 50% DA, an OPS/UPS pension of ₹37,500 becomes ₹56,250/month. NPS annuity remains fixed — losing real value to inflation every year.
6. Who Should Choose What?
Already Under OPS?
If you joined before Jan 1, 2004, you are already on OPS. Do not switch — OPS gives maximum guaranteed security with zero employee contribution.
Want Maximum Lump Sum?
If comfortable with market risk and want a larger retirement corpus, NPS may build a bigger fund — especially if markets perform well over 30+ years.
Best Choice for New Employees
For central govt employees joining after April 2025, UPS is clearly better than NPS — guaranteed pension, higher govt contribution (18.5%), DR protection, better family pension.
Switch to UPS If Eligible
If you have 10+ years of service remaining, switching to UPS is strongly advisable. You get guaranteed pension + inflation protection without losing accumulated NPS corpus.
7. Frequently Asked Questions (FAQ)
Q: Can existing NPS employees switch to UPS?
Yes. The government has given NPS employees a one-time option to switch to UPS. Your accumulated NPS corpus moves to UPS. Most financial advisors recommend switching — especially for employees with 15+ years remaining service who want pension security.
Q: Is UPS pension exactly 50% of last salary?
UPS pension is 50% of the average basic pay of the last 12 months before retirement — not the very last month. In practice the difference is small since salary rarely changes drastically in the final year.
Q: Which state governments have restored OPS?
As of 2025 — Rajasthan, Himachal Pradesh, Punjab, Jharkhand, and Chhattisgarh have announced OPS restoration for state employees. However, implementation varies and faces fiscal challenges. Central govt employees are not affected.
Q: What happens to NPS corpus if I switch to UPS?
Your entire NPS corpus (employee + government contributions + returns) transfers to UPS. The government tops up any shortfall between actual NPS corpus and what it should have been under 18.5% UPS contribution rates. You lose nothing.
Q: Is UPS pension taxable?
Yes — pension received is taxable as income under “Salaries.” The lump sum component and commuted pension are tax-exempt for government employees. Employee contributions get Section 80C deduction.
Q: What if I complete less than 25 years under UPS?
Proportionate pension for 10–25 years. Minimum ₹10,000/month for at least 10 years of service. Below 10 years — accumulated corpus is returned.
Q: NPS vs UPS — which gives more money overall?
NPS gives larger lump sum at retirement. UPS gives higher monthly pension throughout retirement due to guarantee + DR. Over a 20-year retirement, UPS pensioners typically receive more total money — because DR compounds significantly while NPS annuity stays flat.
